Uncovering history with Little Foot's skull

One of our most complete ancient ancestor’s fossils has been transported to the UK from South Africa in order to be scanned at the Diamond Light Source. Roland Pease investigates what these scans could reveal about the human story.

Professor Corinne Le Quéré explains how she managed to look past the 7% reduction in human emissions caused by the pandemic in 2020 to reveal the impact of the Paris Climate agreements, and explains what more needs to be done. Roland speaks with anthropologist Dr. Rolf Quam, who has studied the inner ears of fossilised Neanderthal skulls to reveal they may have evolved the ability to hear the complex sounds of spoken language separately to our own species. Dr. Emma Hodcroft discusses the Brazilian P1 COVID 19 variant that is spreading around the world.

And, The sudden agony of stubbing a toe or burning a finger can make even the most polite among us swear our heads off. It’s like a reflex, a quick-release valve for the shock. But why do expletives give us such a sense of relief? Why does it sometimes feel so good to swear?

We set out to explore the science of swearing, prompted by a question from our listener Gadi. Psychological studies have shown bad language can relieve pain, or even make us stronger; we test out these theories for ourselves, and try to figure out why certain words are charged with such physical power.

We don’t just use strong words in shock or anger, either. They can help us to bond with others, to express joy, solidarity, or creativity. And although people curse all over the world, it’s not quite the same everywhere. We hear what people like to swear about in different countries, and whether swearing in a second language can ever be quite so satisfying.
